shared,gui,cli: Fix intra-file ordering for content search results

group_concat() does not preserve order of the ORDRE BY rank,
making the ordering quite meaningless for pages inside a file.

The recently introduced combobox to filter on a per file basis
should anyway be prefered than any kind of grouping in queries.

So we just remove the groupings here.

"All files" in the previews tab thus should show the best results
first now, from any files part of the result set.

A GUI option to sort by page instead of rank can be considered.
